I am trying to selectAll all value from RadGridView. On ViewModel, I have a ListCollectionView, which represents all value from RadGridView. And i was able to take every value and set IsSelected to true.
foreach (var value in ListCollectionView)
value.IsSelected = true;
On RadGridView; those value that i can see, are highlighted but if i scroll down those i couldn't see are not highlighted.
Is anyone why.
Thank you for help.
